Adjusting the crossover for flattest in-room response

Once a credible and reliable free-field anechoic or quasi-anechoic frequency response is available, it is loaded into the simulator and a theoretical crossover model is developed in the simulator. The next step is to physically build the crossover and then set-up to measure the frequency response of the speaker system with that crossover in-room. ...

In the words of the designer ...

In this series of home-movies, the Harbeth designer talks about where he designs, and talks about some of the issues facing him. Interviewed by journalist Trevor Butler, Alan talks candidly about facets of the process of speaker design where art meets science. ...

Listening to loudspeakers.

The ear has to be deceived into creating invisible musicians in space, between and beyond the physical x-plane of the loudspeakers so the dispersion of the loudspeaker's energy into the listening room has to be carefully controlled by design. ...

Harbeth's history in speaker cone research

The heart of today's Harbeth sound is our unique, Patented, RADIAL cone material. It has an interesting legacy. On 19 March 1976, our founder, H. D. Harwood of the BBC Research Department, filed a Patent application (1563511) claiming that polypropylene could be used as a loudspeaker cone material, ...

Frequency response curves

Here from one of my 1988 log books is a traditional pen-chart trace of a speaker under development. If I couldn't recall which model this prototype would become in production, I could not deduce its name from this curve. ...

Pages from '88, the early days

Here are a few of the first steps along the design path from around the time of the original HL Compact and HL5, launched in 1988/9. In those days of paper-trace pen-charts, the only convenient way to make permanent records was by gluing the trace sheets into bulging Log Books. ...

Flowchart of the design process

Starting with just an idea for a new model, there is a critical path that leads to the product. Loudspeakers can not be designed solely by techicians; they must be listened to and appraised continually throughout the design process. ...
